How to Calculate Quantities of Cement, Sand and Aggregate for Nominal Concrete Mix (1:2:4)? Mix design is a process of determining the right quality materials and their relative proportions to prepare concrete of desired properties like workability, strength, setting time and durability.
In the absence of concrete mixers, concrete can also be mixed manually. However, this is applicable to only small amounts of concrete. Additionally, workers are prone to mix concrete poorly and, in many cases, end up over-mixing it. Hence, it is advisable to use machine mixers to mix concrete materials. Concrete Mixer Background

Sand and cement are typically used at a ratio of about 1 to 1, although some mix designs call for slightly higher cementitious materials content (see "GRFC Mix Design," Concrete Décor, June/July 2008). With its high cement content and low water-cement ratio (0.33 to 0.38), GFRC can dry out quickly and not gain full strength.
The formula for concrete mix is one part cement, two parts sand and three parts gravel or crushed stone. If hand mixing, it's inadvisable to exceed a water to cement ratio of 0.55, which translates to 55 pounds of water for every 100 pounds of cement. When mixing concrete, it's necessary to ensure that there is an adequate amount of aggregate.
